Adds the `atenc` element capable of encoding AAC-LC audio, using the AudioToolbox framework. It's able to encode up to 7.1 channel configurations. Comes with basic knobs for rate control (bitrate for CBR, quality for VBR). Support for more profiles (LD, HE-AAC) should be simple, but is not included here because of bugs with parsing of the AudioSpecificConfig.
